Incorrect protocol url and scope prefix used for MSOffice365Protocol

When using MSOffice365Protocol as the protocol, during authentication it always fails with error

Unable to fetch auth token. Error: (invalid_client) AADSTS700025: Client is public so neither 'client_assertion' nor 'client_secret' should be presented.

The issue was found to be the following

class MSOffice365Protocol(Protocol): _protocol_url = 'https://outlook.office.com/api/' _oauth_scope_prefix = 'https://outlook.office.com/'

After changing it to the following, it seems to work fine

_protocol_url = 'https://outlook.office365.com/api/' _oauth_scope_prefix = 'https://outlook.office365.com/'

Hi, I’ve further studied this issue.

You have to set the redirect uri. It’s not enough to check the checkbox for the redirect uri. You have to set the redirect uri text box with the desired redirect uri.

In the following image you can see that the textbox redirect uri is not set.

See #317

@rayeeskm can you check that? @Narcolapser is this your case?

On the contrary if you have set a public client on purpose… well this library is not yet prepared to handle a device authentication flow.
